x+2 1/2 <8
To solve the inequality x + 2 1/2 < 8, we can first subtract 2 1/2 from both sides to isolate the variable x:
x + 2 1/2 - 2 1/2 < 8 - 2 1/2
This simplifies to:
x < 5 1/2
Therefore, the solution to the inequality x + 2 1/2 < 8 is x < 5 1/2.
solve -5x>20
To solve the inequality -5x > 20, we need to divide both sides of the inequality by -5. However, when dividing by a negative number, we need to reverse the inequality symbol.
Dividing both sides by -5, we get:
x < -4
So the solution to the inequality -5x > 20 is x < -4.
6x<54
To solve the inequality 6x < 54, we can divide both sides of the inequality by 6:
6x/6 < 54/6
x < 9
Therefore, the solution to the given inequality is x < 9.
3.4x>23.8
To solve the inequality 3.4x > 23.8, divide both sides of the inequality by 3.4:
(3.4x) / 3.4 > 23.8 / 3.4
x > 7
Therefore, the solution to the given inequality is x > 7.
8x-14<10
To solve the inequality 8x - 14 < 10, we first add 14 to both sides to isolate the variable x:
8x - 14 + 14 < 10 + 14
This simplifies to:
8x < 24
Next, we divide both sides of the inequality by 8:
(8x) / 8 < 24 / 8
x < 3
Therefore, the solution to the given inequality is x < 3.
